Hi,

We dont think that its an issue with avast!, since the avast configuration is same on both the computers. So please note down the error message that you get while trying to update Chrome and you can try the following link for the fix.

Please update back if it didn’t work.

Have a wonderful day. Good Karma! :slight_smile:
